This will allow clinicians to monitor changes in balance and potentially track the effectiveness of interventions aimed at improving balance.</p>","PeriodicalId":54276,"journal":{"name":"Sports Health-A Multidisciplinary Approach","volume":" ","pages":"619-628"},"PeriodicalIF":2.6,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12084217/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144082071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
